The 3 inch high flow flap valve, Bushman part number 39034, goes on the end of a rainwater tank overflow pipe and keeps mosquitoes, frogs, birds and other pests out of the pipework.
How it works
The plastic flap opens when water flows and closes when it stops. It is double sealed, self cleaning, cannot be turned past open, and is vented so air and water move smoothly during rain. It fits the end of a 3 inch Schedule 40 overflow pipe, such as the one from the 3 inch Tank Overflow Kit, part 39026, on 100 to 1150 gallon rainwater tanks. The 4 inch version is part 39033.
